Regis was killed in 2375 as the result of retaliatory attacks on the Equinox crew by a series of nucleogenic lifeforms, whom the crew had been murdering for the purpose of converting the remains into a source of fuel. After the surviving Equinox crewmembers were rescued by the crew of the USS Voyager, Regis's name was mentioned during a memorial service aboard that ship. (VOY: "Equinox")
